The medium glass was made from chemical compounds with a composition (70-x) P2O5 - 10Bi2O3 - 10Na2O - 10Gd2O3 - xDy2O3 (where x = 0; 0.05; 0.1; 0, 5; 1.0; 3.0 (mol%)) which is doped by active ion xDy2O3. All of propofed chemical compounds are in the form of powder with a mass of 20 gram of mixture in an alumina crucible and prepared by melt-quenching method. The glass that has been obtained with a size (3x10x10) mm3 and smoothed to get a flat surface and high transparency. Optical properties of glass samples Dy:PBiNaGd determined by measuring by absorption spectrum and spectrophotometer at area visible with different consentration. Analysis indicate eleven inhomogeneous displacement bands at various positions and intensities with hypersensitive transitions at 1274 nm (6H15/2→6F11/2). Emission spectrum in medium glass Dy:PBiNaGd is supported using excitation wavelength (λeks) 350 nm and indicated that the highest intensity is in Dy:PBiNaGd4 where there four transition band emisin are namely 4H9/2 → 6H13/2 (483 nm), 4H9/2 → 6H11/2 nm), 4H9/2 → 6H9/2 (661 nm) and 4H9/2 → 6H6/2 (750 nm).
